Subject: [PATCH 4/8] s390: qeth: wrong packet length in qdio header
Date: Wed, 20 Jun 2007 12:59:14 +0200 [thread overview]
Message-ID: <20070620105914.GD9454@de.ibm.com> (raw)
In-Reply-To: <20070620104817.GA2627@de.ibm.com>
From: Frank Pavlic <fpavlic@de.ibm.com>
Packets Length in qdio header is broken when using
EDDP on Layer2 devices. This leads to skb_under_panic on receiver
system when running on z/VM GuestLAN devices.
